Hi there !!! I've installed chan_ss7-0.9 on my Asterisk 1.2.16 and Zaptel-1.2.15. My zaptel.conf: atualss7:/etc/asterisk# cat ../zaptel.conf span=1,1,0,ccs,hdb3 bchan=1-31 span=2,0,0,ccs,hdb3 bchan=32-62 loadzone = us defaultzone=us My ss7.conf atualss7:/etc/asterisk# cat ss7.conf [linkset-siuc] enabled => yes enable_st => no use_connect => yes hunting_policy => even_mru context => ss7 ; The value and action for t35.

My SS7 tech guy says he is receveing: Astk: IAM REL-29, than my PSTN answers with a RLC, but nothing happens, my softfoen keeps ring until gets a timeout. My PSTN PBX, where SS7 Link is connected is a SPTel DSX-100. Any help would be great. Because we're needing to install another 10 links exactly like that using chan_ss7.
